If left untreated, STIs not only are uncomfortable and embarrassing but also can seriously affect your health and fertility.

Preventing STIs

You can reduce the risk of STI transmission during oral sex by making sure you or your partner wears a condom.

You can use a dental dam to cover the anus or female genitals during oral sex. A dental dam is a latex or polyurethane (very thin, soft plastic) square, of about 15cm by 15cm. It acts as a barrier to help prevent STIs passing from one person to another.
